How to clear cache files on Mac
Cache is basically technical data that is stored when an app, browser, or system performs a task. Cache files serve a vital function as they contain a “shortcut” to a task in order to perform it faster next time you need it.
Why should you clear cache on Mac?
Cache is meant to help your Mac load sites faster, but sometimes it brings more harm than good. For example, if the website you’re about to visit has been updated ever since your Mac cached its data, your browser will still load the outdated cached version of the site. Outdated cache may be the reason why some websites behave laggy.
Old cache files that remain latent in the system do nothing but pile up, cluttering your system folders. What was initially useful becomes a drag, slowing down your Mac through all the wasted space it is taking up. To make it even worse, undeleted cache data also leads to task conflicts and other system issues.
It’s staggering how much space can, in fact, be occupied by app/user cache on Mac. Wondering how much storage you’ve lost already? Well, it’s different for everyone, but it’s safe to assume several gigabytes at the very least.
Types of cache files
Here are the three main categories of cache data:
These are cache files your macOS generates to retrieve data you need in no time. With their help, system services run more quickly.
Also known as user cache, these are files generated by applications installed on your Mac, including preinstalled and third-party apps. They store images, search history, and any other information you, as a user of an app, may need to work with it flawlessly.
How to clear all types of cache on Mac step by step
Now, if you’re ready to finally get down to business, we’re going to walk you through both the manual and the automatic solutions to clearing your cache.
To play it safe, back up the folders mentioned in the steps below. If everything works as it should, you can later delete these backups. We suggest starting with the easiest way to clear cache on Mac — automatic cache removal with the help of a dedicated Mac cleaner app. But you can skip it and jump to manual removal if you're in the mood for some detective work.
How to clear all types of cache at once
Clearing caches manually is a tough nut to crack. To do the job in a fraction of time and without the risk of losing something important, you can fire up a dedicated cache cleaner app, CleanMyMac X. It will find and clear all your app caches blazing fast. See how easy it is with these steps:

- Open the app and go to System Junk from the sidebar.
- Click the big Scan button.
- When it’s done scanning, click Review Details to see what it has found.
User Cache Files contain app and browser cache. If you use lots of apps, cache can accumulate quickly and take up a lot of your disk space.
When the scan is complete, click the Clean button to clear the cache and other junk.
How to manually clear system cache on Mac
System cache doesn’t take much space, as it’s usually files generated by macOS. You need to be particularly careful when clearing the system cache manually, though, to avoid erasing vital system files.
To remove the system cache completely, follow these steps:
- Open the Finder and click Go > Go to Folder from the menu bar.
- Paste the following path /Library/Caches and press Return.
- Don’t delete folders: you can only clear what’s inside of them. When you’re done, just empty the Trash to finish the job.
How to remove app cache on Mac
To delete the app cache (which is also called the user cache) manually, follow these steps:
- Open the Finder and select Go > Go to Folder.
- Type in ~/Library/Caches (note the ~) and press Return.
- Optional step: copy the files somewhere else in case something goes wrong.
- Keep the folders, but go into each one and delete the files inside.
- Empty the Trash.
